From the foregoing description the use and operation of our improveddevice will be readily understood. After the receptacle has been filledthe cap is placed in position and the bail made to engage the recesseson the opposite sides of the receptacle in the usual manner. The bail isthen raised until its transverse part engages the curved projection orcam (1 of the cap (I. This transverse part of the bail is then movedupwardly until it engages the recess C. It will be understood that sincethe part C of the cap curves u 'iwardly from the base or lower portionof the cap the transverse part of the bail will be bowed upwardly asitapproaches the central position or the reccss (l of the sap. It willalso be understood that the degree of the curve of the part G of the capmay be regulated as desired, whereby the necessary pressure may be givento the cap through the instrumentality of the bail when the latter is inthe locking position.

' Havingthus described our invention, what we claim is- 1. Thecombination with a bottle, jar or similar receptacle, of a bail whoseextremities are pivotally connected to the opposite sides of thereceptacle, and a closure applied to the top of the receptacle andhaving a cam-shaped projection formed on top thereof and adapted tospring the transverse part of the bail upwardly, as the latter ismovedto a central position transversely of the said projection, thecover being provided with recesses located on opposite sides of thecam-shaped projection for the purpose set forth.

2. The combination with a receptacle of the class described, of a cap orclosure applied to the top of said receptacle and having anupwardly-projecting cam-shaped part which is highest at the top, thesaid cam-shaped part having smooth edges and a shallow central recess atthe top, and recesses on opposite sides of the can1shaped part, and abail centrally pivoted in the opposite sides of the body of the vesseland having a transverse part adapted to engage the earn-shaped part ofthe cap, whereby as the bail is moved upwardly to the center of thecam-shaped part, the said bail is placed under tension and engages thecentral recess at the top of the cap, substantially as described.

In testimony whereof we aflix our signatures in presence of twowitnesses.
